MOBILE, Alabama -- A spate of four homicides in four days came full circle Sunday evening with the shooting death of a man who was closely tied to the Thursday killing.

The man, identified Sunday as 25-year-old Darius Longmire, was found by police Thursday locked in the trunk of a car. Longmire was unharmed, but 2 men just outside the car had been shot, one of them fatally.

Then Sunday, police Officer Christopher Levy said, Longmire was fatally shot several times while in the 1500 block of Eagle Drive in the Birdville community, just north of Brookley Industrial Complex. He was pronounced dead on the scene.

Police got a report at 5 p.m. Sunday about a shooting on Eagle Drive, Levy said, and they found Longmire.

Less than a day earlier, 28-year-old Sary Kinn was found shot to death on an industrial road in the south end of Hollinger’s Island, according to police.

Levy said police got the call at 10:50 p.m. Saturday for a man down in the 7700 block of Deer River Road East. Responding officers found Kinn lying partly on the pavement with multiple gunshot wounds, he said.

Kinn, who died at the scene, was found on a curve in the road about 200 yards east of the fork where Deer River Road East breaks off Deer River Road and eventually leads to the Millard Refrigerated Services plant on the north bank of the Theodore Industrial Canal.

There was no evidence tying Kinn’s death with any others, Levy said, and it was too early in the investigation to determine if Kinn was shot at the scene or shot elsewhere and dumped where he was found.

Early Friday morning, Ramon Tinson, 23, was killed in a car at Government Street and Dauphin Island Parkway in what police believe was a drive-by shooting.

There was also no evidence tying his death to any of the others, Levy said.

As of Sunday night, no arrests had been made in any of the four killings.

The man killed on Thursday was identified as Michael Watkins, 24, and the identity of the other man, who was shot in the face and did not die, was not released.

At the scene of the shootings, Longmire was found locked inside the trunk of an iridescent purple Chevrolet Caprice in a vacant lot off Abrams Street and Spring Hill Avenue, near Interstate 65.

Longmire was questioned by police, according to Levy.

Levy said that anyone with information about any of these cases is asked to call police at 251-208-7211, CrimeStoppers at 251-208-7000 or text to 274637 and include the keyword CRIME 411.
